Hello and welcome to TSF.

I guess you learned your lesson. It only takes a few seconds to get infected if you don't have any protection software. If you needed space, you should have uninstalled the NON-SECURITY programs that you no longer use or need. Windows Defender alone is not enough to protect your system.

The system appears to be severely compromised with a backdoor trojan among others. A backdoor trojan runs in the background and allows remote access to the compromised system, stealing critical system information, downloading and executing files without the knowledge of the owner.

If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

In all honesty, if this were to be my computer, I would back up all my personal data and do a reformat&reinstall. Please read this: How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

However, if you do not have the resources to reinstall your computer and would like me to attempt to clean it, I will be happy to do so but it is not fully guaranteed that your computer will be completely rid of malware regardless of what anyone can really do.

If you haven't received help elsewhere already and still wish to try to clean it, please post the logs requested in our pre-posting process outlined below:

If you have trouble with one of the steps, simply move on to the next one, and make note of it in your reply.

Please note that the forum is very busy and if I don't hear from you in three days this thread will be closed.
